Update: 

  • A judge dismissed a class action lawsuit filed by a group of vehicle owners against Hyundai Motor Co. in a California federal court. 
  • The class action lawsuit claimed a number of Hyundai and Kia model vehicles contained an engine defect that caused them to use an excessive amount of oil.
  • The vehicle owners argued the alleged defect, in addition to costing them money for the excess oil, caused the vehicles to stall and eventually fail. 
  • Court approval of the dismissal was not required as the class had not been certified nor proposed to be certified for purposes of a settlement, according to court documents. 

Hyundai excessive oil consumption class action lawsuit overview:

  • Who: A group of Hyundai and Kia vehicle owners are suing Hyundai Motor Co.

  • Where: The lawsuit was filed in a California federal court.

(April 20, 2022)

Hyundai makes numerous models of Hyundai and Kia brand vehicles with defective engines that use excessive amounts of oil, costing their owners huge sums of money, a new class action lawsuit alleges.

On Apr. 12, eight owners of Hyundai and Kia brand vehicles filed a class action lawsuit against Hyundai Motor Co. in a California federal court, alleging violations of federal warranty laws.

The Hyundai excessive oil consumption lawsuit alleges that numerous models of the automaker’s vehicles are equipped with defective Nu, Gamma, Theta, Lambda and Kappa engines.

The defective engines allegedly use excessive amounts of oil, stall and eventually fail. The drivers say Hyundai should have issued a recall for the vehicles a long time ago but hasn’t.

As a result, thousands of Hyundai and Kia owners and lessees have allegedly been forced to constantly check the oil levels, and oil must be added to the engines more frequently than even the owner’s manuals recommend, Car Complaints reports.

The engine issue has flow-on effects like reduction in engine lubrication due to crankshaft submersion and gaskets and seals damage, which leads to oil leaks.

The plaintiffs also claim that oil in their vehicles migrates to places where it shouldn’t be, damaging the combustion and exhaust systems.

This allegedly causes “abnormal wear of engine parts, oversaturation of carbon and deposits of oil sludge, ultimately requiring a costly engine rebuild or replacement.”

Automaker should honor warranty claims outside terms, Hyundai class action says

The plaintiffs allege that Hyundai should honor customers’ warranty claims even when the warranties have expired. 

According to the lawsuit, Hyundai can’t adequately repair the oil consumption problems and doesn’t offer any reimbursement for out-of-pocket costs caused by the issue.

The class action states customers must suffer through long wait times for replacement parts, “and in most cases do not receive required engine replacements.”

The cars with the allegedly faulty engines include the 2012-2020 Hyundai Elantra, 2009-2018 Hyundai Genesis Coupe, 2019-2021 Hyundai Kona, 2020-2021 Hyundai Palisade, 2010-2012 and 2015-2021 Hyundai Santa Fe, 2009-2010 and 2015-2021 Hyundai Sonata, 2011–2021 Hyundai Sonata Hybrid, 2010-2013 and 2015-2021 Hyundai Tucson, 2011-2021 Hyundai Veloster, 2020-2021 Hyundai Venue, 2010-2021 Kia Forte, 2017-2020 Kia Niro, 2011-2020 Kia Optima and Optima Hybrid, 2012-2021 Kia Rio, 2011-2020 Kia Sorento, 2012-2021 Kia Soul, 2011-2020 Kia Sportage, 2018-2021 Kia Stinger and 2022 Kia K5.

Meanwhile, Hyundai has expanded its recall of vehicles with an exploding seat belt part issue that has caused multiple injuries to include 6,240 of its 2021-2022 Elantra and 2020 Accent vehicles. 

The plaintiffs are represented by Nye, Stirling, Hale & Miller LLP, Sauder Schelkopf LLC and Walsh, PLLC.

The Hyundai Oil Consumption Lawsuit is Cho, et al., v. Hyundai Motor Company, LTD., et al. in the U.S. District Court for the Central District of California.

    2014 sonata, high oil use between oil changes. Contact me.

  2. Stephanie A Balch-Kelly says:

    We purchased a 2021 Hyundai Palisade brand new, and have had nothing but problems. The car is burning upwards of two quarts of oil between the manufacturer’s recommended oil changes. We’ve gone through consumption checks every 1,000 miles, and were told that having the car burn between 1/2 and 1 quart of oil every 1,000 miles is within industry standards. We need help!!!

  3. Carmelo Belardo III says:

    I own a 2015 Sonata and add at least one quart of oil per week which is ridiculous. How do I get on the plaintiff list for the class action suit?

    1. Horace Mckenzie says:

      My wife has a 2015 kia sante fe and we’ve noticed the car is using extremely too much oil maybe a quart every 300 miles this her only transportation too work if it broke down she could loose her job

  4. Linda says:

    I have a 2015 Sonata and it started burning oil sometime last year, that I can remember. I’ve wasted so much money with mechanics and buying oil. It’s very frustrating! I changed the spark plugs and the gaskets and it’s still burning oil. I have to check the level every 2-3 days and constantly add oil. I’m hoping to get rid of it soon and I will never purchase another Hyundai again!

  5. Marcelo Cisneros says:

    I have a 2017 Hyundai Tucson. Sport… it has been burning oil since I can remember and it keeps getting worst. Dealer keeps saying it is normal for engines to burn oil that frequently. Never had any issues with other automobile makers (Ford, Honda) It’s at 80k miles now and the warranty will run out soon. Please send me the info of the lawsuits and add me as well.

  6. Tiffany Marie Williams says:

    I have a 2016 Hyundai Veloster a check engine light came on 2 months after purchase 75,000 miles. The dealership said I needed a new engine for 9,000 but couldn’t tell me what the problem was. I took it to a different Hyundai dealer and they said it would cost 1400 to fix the next day the light was back and they said their tests didn’t have a result for the indicator, but I needed an oil change. Got an oil change June 2022, in August it was completely dry. Just checked it and its dry again. There is also a knocking noise. How do I join class action?

  7. Martha says:

    My 2017 Tucson caught on fire and burnt totaling it on August 29, 2022

  8. Terry Statton says:

    My 2017 Hyundai Santa Fe Sport is using oil at a fast rate. I checked my oil and it was almost 4 quarts low and was 500 miles under the recommended mileage for oil change. I called the Hyundai service rep that I use and he said that using 1 quart per 1,000 miles was within range. Something is wrong!

  9. Amy Honaker says:

    I believe my 2017 Hyundai Elantra is burning a lot more oil than in the past within within a month I’ve had to fill my oil twice with 2 quarts each time. And I do believe it is causing some issues. Stalling and some sounds that are not normal. But once I fill the oil no issues until its low again. But now that I’m aware I can check it more often.

  10. Christine Bryan says:

    2017 hyundai elantra value edition. I have to add atleast a qt of oil every 300 miles. I see no visible leaks. This is insane!. It may be less than 300 miles, still checking frequency. Constant checking and cost of maintenance should be rectified. Thank you

    1. Theresa Deeds says:

      I also have a 2017 Elantra value addition I thought I was just imagining having to put oil in because It’s so new. I’m the second owner and have only had it a year.
